Specification of Letters Patent.

MATERIALS.

Patented Aug. 2%,1912.

Application filed August 16, 1909. Serial No. 513,112.

Be it known that I, EVELYN P, SPERRY, a citizen of the nited States,-residing in Oak Park, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Beaters for Beating and Aerating Eggs, Cream, Batter, and other M aterials, of which the following is aspecification.

This invention relates to that class ofbeaters which are adapted to be used for beating, mixing and aerating eggs, cream,

preferably annular walls of the vessel in.

batter, custards or other materials.

The principal object of the invention is to provide a simple, economical and efficient egg beater or beater for mixing, beating and aerating eggs, cream, batter or similar materials.

A further object of the invention is to provide a heater which is adapted to thoroughly beat, mix and aerate efficiently, and

with substantially the highest possible degree of facility, comparatively. small or large quantities of eggs, cream batter or other materials. 1

A further" object is to provide a beater having one or more wheels mounted upon a suitable rotary support, shaft or spindle,-

'rial thrown outward by the wheels inward and into position to be repeatedly operated upon by the wheel or wheels as it passes between the peripheral edges of the latter and the inner edges of the side bafile or baflies, said bow also forming a support for the bottom of the spindle or wheel support, and

forming bottom battles adapted to divert the material upward from the bottom of the vessel into or between the blades of the wheel or wheels. Theoutward movement of the material operated upon is limited by the which the beater mechanism is mounted. Either a comparatively large or a comparatively small quantity of material may thus sence of such bafiies, and wheels of a given size are thus enabled'to operate efficiently and with the greatest possible degree of faacomparatively small quantity of material, and in either a large or comparatively small vessel. By providing, in combination with the above elements, one or more removable side battles or wings the wheels may loeof a size adapted to operate in an eiiicient manner uponthe smallest desired quantity of material, or in the smallest desired size 'of. vessel without the removable bafiies or wings, and the baflies will enable the machine with such relatively small wheels to operate in an efficient'manner upon a comparatively great quantity of material and in a comparatively large vessel when required,

cility upon either a comparatively large or I the facility of operation'and the capacity of the machine with wheels of a given size being greatly increased by both the permanent and the removable baflies.

The invention consists j in the features, combinations, and details of construction herein described and claimed, and illustrated in the accompanying drawings which are made a part of this specification. In theaccompanying drawings Figure 1 is a view "in" elevation: of a beater constructed in accordance with my improvements; Fig. 2, a sectional plan View, taken on line 2 of Fig. 1, looking in the direction of the arrow;

Fig. 3 a side elevation, with the removable baflles or wings shown in Figs. -1 and 2, removed; Fig. 4 an enlarged detail view in section of the wheel shown in Fig. 2; Fig. 5, a detail view in elevation showing the bow orbattles in perspective; Fig. 6, a top yiew of a removable bafiie or wing,'and Fig. 7, a detail view in side elevation of the removable bafile or wing shown in Fig. 6, and

vFig. 8 a detail view in sectional elevation showing two wheels on the same spindle, both adapted to throw upward and outward.

In constructing a beater in accordance with my improvements I provide. one or more wheels aeach having a series of radial wings I) all formed preferably of one integral iece of sheet metal, and havingthe hub c in a ditferent plane from the rim d which connects the outer tips or corners of the blades or wings Z). A plurality of these wheels may be mounted on the same support or spindle e. When only one wheel is used I prefer to have the radial blades so inclined as to throw upward and outward, or

in other words each blade is inclined'upwardly and rearwardly from its forward edge so as to throw outward and upward.

The top wheel, however, may be inverted so that its blades are inclined downward and rearward from their forward edges respectively.

The top end of the spindle is journaled in a supporting frame member f having a handle g by which the device may be held in one hand while the other hand of the operator is employed in turning the crank or gear wheel by means of which the beater wheels nism. A cover m for the vessel 02 may be secured to the stationary portion of the frame of the heater" or form a part thereof, when required. The cover should he provided with perforations 0 for admitting air by which the material to be operated upon may be aerated.

The stirrer .or heater wheels may be adjusted to any desired osition up or down on the spindle or to di, erent distances from each other by providing one or more of said wheels witha set screw or cotter p. A bow g having upwardly and downwardly extending sidev blade portions 1' may be secured to and rotate with the spindle, or may be secured to and form a part of one of the beater wheels, or. to both the spindle and wheel as-shown in Figs. 1 and 2. The side blade' portions of this how extend inward ,and rearward from their outer edges with .respect to the direction of rotation, so as to throw the material inward from thelinner edges of the side bafiles hereinafter described, and the upper portion of the bow forms inclined to the direction of rotation.

transverse blades s the bottom surfaces of which are inclined downward and rearward from their forward edges and with respect A frame member or bow at secured to the frame member 7 by means of a rivet u,'and having its upper end portions set into sockets or counter-sunk portions '0, is so arran ed that its side portions 'w form baffles outslde of and adjacent to the peripheries of the beater wheels. The inner faces of these side bafiles extend inward and forward with respect to the direction of movement or ro-' tation of the adjacent peripheries of the beater wheels so as to divert thecurrent of material operated upon inward from the side wall of the vessel toward, into and between the beater wheels and the blades of'the lat-3 ter. The bottom portion of the. bow or frame member It forms bottom baflies y, the

upper sides orsurfaces of which extend upward and forward at an incline with respect to the direction of movement of the adjacent portions of the beater wheel which is directly over said bottom baffles. The

blades of the bottom wheel and the'bottom baffles thus both tend to throw the material the wheels to be again thrown outback of each side 'baflle repeatedly or successively, and is thus thoroughly intermixed, beaten andaerated. 7

Removable wings or sidebaflles 2 made to conform somewhat to the sizefform and dimensions of the vessel in which the device is to be used or forming a part of the device, are removably mounted on the side battles, to which they are removably secured in any ordinary and well known manner, prefer ably by means of clips or tongues 2 and 3 adapted to engage opposite sides of the ermanent'baflles and hold the removable affies, wings or blades in operative position.

The tongues 2 are bent inward so as to form shoulders or hook portions 4 adapted to engage the permanent battles and increase the security of the connection between the parts. -The tongues or clips 2.-and 3, are flexible, and the wings a are also preferably flexible, and adapted to be bent to the desired incline, and to the desired. extent for the purpose of conforming to the different sized vessels in which the device is to be used. from time to time. The removable wings are preferably so arranged that they extend inward and forward at an incline from their outer edges with respect to the direction of movement of the adjacent peripheries of the beater wheels and the diin an eflici'ent manner a muchlarger quantity of material than would be practicable with wheels of the same size Without the bafiies, I
